Due to the specific feeding scheme and asymmetry introduced in the triangular cavity, the resonator exhibits four sharp Fano-like resonances. The behavior of the structure is analyzed in detail and its sensing capabilities demonstrated through the responses for various refractive indices. The results show that the sensor has very good sensitivity and maximal figure of merit (FOM) value of 3.2 × 105. In comparison to other similar sensors, the proposed one has comparable sensitivity and significantly higher FOM, which clearly demonstrates its high sensing potential.</p></article> Plasmonic sensor metal-insulator-metal Metal-insulator-metal triangular cavity Chemical technology 0103 physical sciences Fano resonance; metal-insulator-metal; plasmonic sensor; triangular cavity Fano resonance TP1-1185 Triangular cavity plasmonic sensor 01 natural sciences Article Nikolina Jankovic, Norbert Cselyuszka, 2018-01-19 journalpaper <?xml version='1.0' encoding='UTF-8'?><article><p>In this paper, we present a Fano metal-insulator-metal (MIM) structure based on an isosceles triangular cavity resonator for refractive index sensing applications.
